| Abstract: | A method for separation and determination of vitamin E from egg by reverse phase HPLC was introduced.The accuracy and precision of this method were much better than the ordinary method. Standrd deviation of retention time and peak area were 0.012 and 146.92, and the corresponding coefficient of variation was 0.22% and 0.44% respectively. The recovery rate was 100.6 ±3%. This method was suitable for measuring VE in egg, milk powder and cod-liver oil. |
